NEC has developed an eco-friendly cooling system for CPUs, said to use 60% less energy than a water-cooling system and even 80% less than an air-cooling system. The core of the system is a liquid chlorofluorocarbon (CFC) substitute, which circulates around the CPU to draw away heat and has low greenhouse effects. NEC says the refrigerant begins boiling at around 50oC, changes … [Read more...]
Compact Water-Circulation System Prevents Stacks of Electronic Chips
A research team from the A*STAR Institute of Microelectronics and Nanyang University in Singapore has designed and built a water circulation system to cool stacks of integrated electrical circuits. “The heat must be removed from microchips to maintain a temperature within acceptable limits: less than 100 °C,” explains team-member Navas Khan from the Institute of … [Read more...]
±0.5% Tolerance Chip NTC Thermistors
Murata Electronics North America added the ±0.5% tolerance option to its NCP series negative temperature coefficient (NTC) thermistor line. The ultra-tight tolerance thermistor is offered for consumer, industrial and automotive temperature ranges (-40°C to +150°C), and provides a low-cost alternative to integrated circuit (IC) based sensing solutions when high sensing accuracy … [Read more...]
Thermostatically Controlled Fan Cord
Gardtec Incorporated’s Green Fan Cord, a thermostatically controlled fan cord, allows AC fans to turn on/off as system ambient temperature calls for additional cooling. The fan cord will turn on cooling fans as ambient temperatures reach the upper 80s Fahrenheit, then turn off cooling fans as temperatures return to the lower 80s. Learn more from Gardtec Incorporated. … [Read more...]
High-Performance Thermal Putty
Fujipoly has released SARCON XR-Um-Al, a thermal interface silicone putty. The gap filler compound’s putty-like consistency contributes to the material’s low contact and thermal resistance while maintaining a thermal conductivity of 17 watt/m-k. SARCON XR-Um-Al is manufactured with a thin aluminum carrier film for customer-friendly application. The low adhesion aluminum barrier … [Read more...]
